The driving handle 306 is a cam-like structure. One end of the driving handle 306 protrudes to form a protrusion 3062 , and the other end is recessed to form a first recess 3064 . The protrusion 3062 enters the top cover space 3022 through the first mounting hole 3024 .

The fixing piece 308 , the extrusion block 310 , the positioning piece 312 and the limiting piece 314 are located in the top cover space 3022 of the top cover 302 . The fixing piece 308 and the extruding block 310 are fixed on the protrusion 3062 of the driving handle 306 , and the extruding block 310 is located at an end away from the driving handle 306 . The positioning member 312 is located at a position corresponding to the second mounting hole 3026 . The limiting member 314 is located at a position corresponding to the third installation hole 3030 .

The fixing piece 308 is a sheet structure, and one end of the fixing piece 308 is provided with a notch 3082 . The extruding block 310 passes through the round hole 3040 on the partition plate 304 and abuts against the cam 242 of the extruding plate 24 . Two balls 3102 are arranged at both ends of the extruding block 310 . The balls 3102 can rotate relative to the extruding block 310 . The positioning member 312 leans against the support portion 3042 on the partition 304 , and is an arcuate structure with two elastic protrusions 3122 respectively provided at both ends. The elastic protrusions 3122 are formed by protruding from both ends of the positioning member 312 . The elastic protrusion 3122 passes through the second mounting hole 3026 on the top cover 302 and snaps into the first recess 3064 on the driving handle 306 to limit the movement of the driving handle 306 . The limiting member 314 abuts against the positioning portion 3046 , and a part of the limiting member 314 passes through the third installation hole 3030 . External force can push the limiting member 314 to move in the third installation hole 3030 . Two second recesses 3142 are formed by recessing the two ends of the stopper 314 against the side of the positioning part 3046. In the process of pushing the stopper 314, the positioning protrusion 3048 of the positioning part 3046 will be pushed out from the two second recesses 3142. Squeeze in or out. During this process, the U-shaped groove 3049 provides elasticity.

During assembly, the spring 26 is sleeved on the fixed platform 2222, the pressing plate 24 is placed in the accommodation groove 226 and squeezes the spring 26, the partition plate 304 is fixed on the top cover 302, and the screw 40 passes through the sinker on the top cover 302. The head hole 3028 and the second through hole 3044 are then fixed on the fixing platform 2222 to fix the sealing assembly 20 on the cover assembly 30 . The fixing plate 3020 on the top cover 302 is fixed on one side of the box body 12 , and the mechanical waterproof door structure 10 is fixed on the box body 12 and can rotate relative to the box body 12 .

After the mechanical waterproof door structure 10 is fastened to the box body 12 , the driving handle 306 is rotated to drive the fixing piece 308 and the extruding block 310 to rotate simultaneously. One end of the fixing piece 308 is turned into the fixing groove 1245 in the box body 12 , and the mechanical waterproof door structure 10 is fixed in the box body 12 . The two ends of the extruding block 310 move from the second end 2426 on the inclined plane 2422 of the cam 242 to the first end 2424. During this process, the extruding plate 24 is extruded, and the extruding plate 24 extrudes the sealing plate 22. The inner surface of the sealing ring 224 makes the sealing ring 224 press against the side wall 124 of the box body 12 to achieve the function of sealing and waterproofing. The flange 2242 enables the sealing ring 224 to achieve a better sealing and waterproof effect.

When the mechanical waterproof door structure 10 needs to be opened, the driving handle 306 is rotated in the opposite direction, and the fixed piece 308 is rotated out from the fixed groove 105 in the box body 12, and at the same time, the two ends of the extrusion block 310 are pushed out from the first position of the inclined surface 2422 on the cam 242. The end 1 portion 2424 moves to the second end portion 2426 and the compression block 310 releases pressure on the compression plate 24 . The sealing ring 224 is no longer under the pressure of the extrusion plate 24 , so that the sealing ring 224 cancels the extrusion on the side wall 124 of the box body 12 .

In this embodiment, the sealing plate 22 is made by secondary molding. For the first time, a rigid material is used to form the support plate 222 portion. For the second time, soft material is used to form the sealing ring part.

In this embodiment, when the mechanical waterproof door structure 10 is fastened or opened, the flange 2242 has no pressing effect on the inner walls around the box body 12, and the present invention solves the problem that it is difficult to switch due to excessive interference question. In order to position the driving handle 306, a positioning member 312 is provided, and an elastic protrusion 3122 is provided on the positioning member 312. The elastic protrusion 3122 snaps into the first recess 3064 on the driving handle 306 . In order to make the rotation of the driving handle 306 more flexible, a support portion 3042 is provided. In order to prevent misoperation, the mechanical waterproof door structure 10 is opened by wrongly turning the drive handle 306 . This case is provided with a limiting member 314, after the fixing piece 308 is snapped into the fixing groove 105, push the limiting piece 314 to snap into the gap 3082 of the fixing piece 308 so that the fixing piece 308 cannot move. In order to position the limiting member 314, a positioning portion 3046 is provided. In order to reduce the frictional force of the extrusion block 310 moving on the slope 2422 , there are two rolling balls 3102 at both ends of the extrusion block 310 .

In another embodiment, at least one cam 242 is arranged on the pressing plate 24, and the cam 242 is linear. Use external force to push the driving handle 306 to push the squeezing block 310 to move on the cam 242 to squeeze the cam 242 . Correspondingly, the shapes of the driving handle 306 and the first installation hole 3024 are changed. The positions of the second mounting hole 3026 and the positioning member 312 are moved to match the change of the driving handle 306 . The fixing piece 308 is pushed into the fixing groove 105 of the box body 12 .

The above is a specific embodiment of the present invention, and its description is more specific and detailed, but it should not be interpreted as a limitation of the patent scope of the present invention. It should be pointed out that, for those skilled in the art, without departing from the inventive concept Under the circumstances, some modifications can also be made, and these obvious replacements all belong to the protection scope of the present invention.
